Manufacturer!Well drilling johnson v wire screen wedge wire screens:

It is necessary to use Johnson v wire screen wedge wire screens to keep loose sand and gravel from collapsing into the borehole. The continuous slot of the filter can support the borehole walls while allowing water to enter the well, casing unslotted is placed above the screen to keep the rest of the borehole open and serve as a housing for pumping equipment. So it is the most important single factor affecting the efficiency of a well, so we also call it"heart of a well".

Application:

Production Methods:

1.Winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods.
